BOTTLE.

SPECIFICATION forming part of Letters Patent No. 650,413, dated May 29, 1900.

Application filed July 15, 1 8 9 9.

To @ZZ whom t may concern:

Be it known that I, JOHN J. ONEILL, a citizen of the United States, residing in the city of New York, borough of Manhattan, county of New York, and State of New York, have invented certain new and useful Improvements in Siphon-Bottles, of which the following is a specification.

This invention relates to Siphon-bottles of the type commonly termed siphons, in which aerated or carbonated waters are contained, and aims to provide certain improvements in such vessels and their caps or heads.

Siphons are generally constructed with a Siphon-head connected to theA mouth of the bottle by being screwed onto a split ring encircling the bottle-neck.l The head maycarry the Siphon-tube or may hold its flange on the mouth of the bottle, so that the interior ofv the head constitutes a valve-chamber above the tube in which ythe valve is operated to permit discharge of the liquid past the valve and out through the spout under the induence of the gaseous pressure within the bottle. Generally in filling bottles of this character the filling-hose has been attached to the spout and the bottle filled while inverted. Much difficulty has been found in expelling all the air from a bottle while filling it, and it has been found impracticable to charge the bottle with syrup by feeding this in through the valve, the density of the syrup interfering very much with such an operation. In attempting to remove as much as possible of the air within a bottle it is customary to snift the bottle several times near'the completion of the filling` operation, snifting consisting in snapping off the hose from the nozzle occasionally to permit a brief discharge of gas from the interior. This is partially successful in expelling the small amount of air remaining in the bottle, but is rarely entirely successful, and this small remnant of air has a peculiar effect on the life of the carbonated water in the bottle, the air seeming to in some way impair the activity of the charge and diminish the internal ejecting-pressure.

My invention aims to provide improvements whereby a Siphon may be easily charged with syrup as well as with aerated waters, whereby its charging can be conveniently and Serial No. 723,886. (No model.)

rapidly effected and whereby a complete assurance against presence of air after charging maybe had.

To this end in carrying out'the preferred form of my invention I provide certainfimmouth of the bottle; H, its neck, and I the. f

split ring for connecting the head tothe bottle. In their general features these parts may be of any usual orsuitable construction.

Referring rst to Fig. l, I will now proceed to describe in detail the preferred form of my invention as shown therein. In this form of my invention I provide between the head and the bottle an intermediate thimble J, having a lower chamber a for passing over the mouth of the bottle and an upper chamber b for c'ommunicating with the interior of the head and an internal shoulder o between these chambers for engaging a packing K to make a leaktight joint around the mouth of the bottle. The thim'ble has the usual internal screwthread d for screwing on the rings I to connect it to the bottle on its lower end, and on its upper end it has external screw-threads e, corresponding in diameter and pitch to those `of the split ring, for engaging it with either the usual head or with my improved head C. According to one feature of improvement I make a leak-tight joint between thehead C and the tube B, as by screwing thel upper end of the tube at f into a socketg in the head and interposing a packing-washer 7i between the end of the tube and the head, above which packing-washer is a small valvechamber t', in which the valve'D works, and I isolate the interior of the head, below the chamber c', from the interior of the bottle and the tube preferably by means of a teat-valve L, which is a rubber or other flexible tube IOO of packing material, preferably formed integrally with the packing-fiange K at top and extending downwardly around the tube, so that it can expand to permit ingress to the bottle, but will embrace the tube to-prevent egress. The teat-valve permits free insertion and vremoval of the tube and prevents escape from the bottle when the tube is withdrawn.- In this way the head can be removed at any time and the bottle charged through the teat- Valve by applying the charging-tube to the thimble, and the tube can be inserted at any time by simply pushing its end through the teat-valve,whi1e the teat-valvc makes's'uc'h a` tight joint that the inter-ier of the head need not be packed where it engages the thimble. I prefer, however, to form an auxiliary duct M, opening above the mouth of the bottle and isolated from the valve-chamber i in the head for charging the bottle, so that the head need not be unscrewed. This duct M hasa mouth N, closed by a stopper O, which is held in position by the bail j of a stopper-fastener P, which straddles the spout F and is fulcrum ed at 7c on each side of the neck Z of the duct M. The duct M and nozzle F are formed by adjacent cores, the core of the duct opening in the chamber m of the head between its internal screw-thread n and the screw-thread g, where the pipe B is attached to the head.

' The duct is in free communication with the chamber b of the thimble, so that at any time by opening the stopper O access to the interior of the bottle can be had for charging it, and the duct is large enough to permit a gravity iiow of syrup or other dense charge into the bottle prior to the introduction of the carbonated charge through it. By use of this duct the bottle can be charged while inverted and the valve can be opened to permit the escape of air during charging. Charging is also facilitated by the shape of the head N, to which the charging-tube may be easily applied, and after charging the charging-tube vmay be removed and the stopper O applied at will, as the teat-valve will act as a checkvalve to prevent escape of the charge from the bottle.

In use it will not be important that the cork Orbe tight, as the teat-valve will prevent` leakage into the chamber b. The passageway through the teat-valve and the chamber b constitntes, essentially, an annular inlet-passage surrounding and concentric with the passage-way through the tube B, which latter constitutes a central outlet-passage. Withthe improved inlet-passage and the teatvalve for closing itthe bottle can be filled in any position with any desired charge,whether or not the head is applied at the time, and the 'head may be applied after filling when desired. The bottle thus equipped can readily be charged with elervescent powders or other substances by the users, so that any user can adapt the contents of a siphou to his particular taste or requirements. Y Effervescent substances or iiavors may be molded into pencil form and forced through the teat-valve before the head is applied, and one head may be used successively on a plurality of bottles, the bottles being stored and shipped with the thimble and neat-valve alone, so that each bottle is ready for application of the head at any time.

Fig. 2V shows a modification in which the teat-valve and thimble are employed with a head which has a special fastening construction and is not provided with my improved duct. This head (lettered 0') has a cavity m', having internal projections n', which enter grooves-2j and 'take under shoulders q in a cylindrical-projection?" on the thimble J', locking the head to the thimble with a bayonetjoint connection. The head has rnyimproved valve-chamber r' and internal thread r, engaged by the thread f of the tube B. A packing-washer 7L makes a tight joint between the tube and head beneath the valve D. The thimble J' has the lower chamber a, top chamber b, intermediate shoulder c, and internal thread d, which screws on the split ring I. The flange K of the teat-valve L is here clamped against the mouth of the bottle by the shoulder c of the thimble. With this construction the neat-valve avoids the necessity of a leak-tight joint between the head and thimble and enables application or removal of the head at any time. The round outer end r of the thimble will be a convenient portion to which to apply the charging-pipe but as this construction necessitates removing the head in order to charge the bottle I prefer to use the improved head before described, With which charging may be effected through the duct M.

If desired, one lnay use the improved charging-duct without the teat-valve and thimble by removing these parts and screwing the head C directly into the split ring, as shown in Fig. 3, an ordinary washer K' being inserted between the shoulder o of the head and the mouth of the bottle. In other respects this construction is identical with that before described and the parts bear the same refernated water or with syrup or with a liquid containing solid matter, the charge being in-v serted through the duct M until the bottle is filled and the charging-pipe being removed once or twice to permit escape of any remnants of air which may accumulate during charging, this process being known as snifting. The stopper will have to be quickly applied after charging, as otherwise there would be nothing to prevent expulsion of some of the charge. Any air in the tube B may be freed during charging by opening the valve D.-

Iu use with rnyimprovements it will be possible for any user to quickly introduce such This construction,

ingredients into a bottle as may be necessary to produce the desired beverage, and the charging can be effected and the bot-tle restored to use with rapidity and convenience. The siphon can be operated for discharging its contents just as siphons are ordinarily oper-ated at present, and the charging can be so perfectly and completely effected that the maximum of life for I(he charge can be obtained.

It will be seen that my invention provides improvements which can be readily and advantageously availed of and that the improved head or the improved thimble can be manufactured as attachments interchangeably applicable to standard Siphon-bottles.

It will be understood that my invention is not limited to the particular details of construction, arrangement, and combination set forth as constituting its preferred form, since it can be employed in whole or in part, according to such modifications as circumstances or the judgment of those skilled in the art may dictate, without departing from the spirit of the invention.
